A Hong Kong business can legitimately use OpenAI’s GPT-5.6 (up to the flagship Sol tier) and Anthropic’s Claude Opus 5 today, without a VPN and without breaching anyone’s terms: GPT through Microsoft 365 Copilot and Microsoft Foundry, and Claude through Copilot’s model picker and Perplexity. That surprises a lot of people, because the headline experience hasn’t changed: ChatGPT.com still errors from a Hong Kong IP, and claude.ai still turns you away. Both are vendor geo-blocks, not government bans (our guide to whether ChatGPT is banned in Hong Kong covers that distinction). This post is the companion piece: not whether the models are blocked, but how to reach them anyway, through the front door. As always with this topic, treat it as a snapshot (September 2026): availability moves fast, and we update these guides when it does.
Every legitimate route at a glance
| Route | What you get | Frontier GPT? | Frontier Claude? | Best for |
|---|---|---|---|---|
| Microsoft 365 Copilot | AI inside Word, Excel, Teams, Outlook | ✅ GPT-5.6 family, up to Sol | ✅ Claude Opus 5 (tenant/region dependent) | Most Hong Kong businesses |
| Microsoft Foundry (Azure) | The models as APIs, for your own apps | ✅ gpt-5.6-sol / -terra / -luna | ⚠️ Listed, but unverified from HK tenants | Developers, custom apps |
| Amazon Bedrock (AWS) | Model APIs on AWS | ✅ GPT models incl. open-weight gpt-oss | ❌ Blocked from HK connections | AWS shops using non-Anthropic models |
| Google Vertex AI / Gemini | Gemini direct; partner models via API | ➖ No GPT | ⚠️ Claude listed, HK access unverified | Google Cloud shops; Gemini users |
| Perplexity | Research assistant with model choice | ✅ GPT-5.6 (Sol on Max) | ✅ Sonnet 5 on Pro, Opus 5 on Max | Individuals, research work |
| Poe and other aggregators | Multi-model chat apps | ✅ | ✅ | Casual use; check terms first |
| Cloudflare AI Gateway | Proxy, billing and caching layer | ➖ Depends on upstream provider | ➖ Same caveat | Developers already on Cloudflare |
The rest of this guide walks through each route, what it costs, and the caveats that matter for a business.
For businesses
Working out which AI route your Hong Kong business should take?
Access is the easy half. The harder half is which route fits your licensing, what data may go through it, and what policy sits behind it. PTS's AI advisory covers route selection, Copilot licensing, acceptable-use policy and the DLP controls to enforce it.
How to use GPT-5.6 in Hong Kong: Microsoft 365 Copilot
The simplest legitimate route to OpenAI’s frontier models in Hong Kong is the one most businesses already half-own. Microsoft 365 Copilot is fully supported here, and since July 2026 its preferred model has been OpenAI’s GPT-5.6 family: three tiers named Sol (the flagship), Terra (balanced) and Luna (fast). Copilot doesn’t show you those names; they sit behind its response-mode labels. But the ceiling is the real thing: the same flagship model that powers ChatGPT’s top tier in supported countries, running inside Word, Excel, PowerPoint, Outlook and Teams, on a Hong Kong tenant, with no workaround.
Because Copilot is licensed through Microsoft rather than OpenAI, none of OpenAI’s regional exclusions apply. You also get what the consumer app can’t give you: enterprise data protection (prompts and responses are not used to train the models), plus DLP, sensitivity labels and audit through standard Microsoft 365 admin tooling. Whether the licence is worth it per user is a separate question, and we’ve written a full assessment of whether Copilot is worth it. Rolled out properly (see Microsoft 365 setup), this is the default answer for most Hong Kong organisations.
How to use Claude in Hong Kong: narrower, but real
Anthropic is the stricter of the two vendors. Hong Kong isn’t on its supported-countries list, the restriction covers the API as well as claude.ai, and enforcement tightened through 2026: several international banks have restricted Claude access for their Hong Kong staff under strict readings of their Anthropic contracts. So the widely-shared assumption (“you just can’t use Claude here”) is closer to true than it is for GPT. Closer, but not correct. Two legitimate doors are open:
Microsoft 365 Copilot’s model picker. Microsoft added Anthropic models to Copilot in late 2025 and has kept pace since: Claude Opus 5 has been rolling out in Copilot since late July 2026, selectable in Word, Excel, PowerPoint, Copilot Chat and Copilot Cowork, Microsoft’s agentic co-working mode where the model works through a multi-step task alongside you rather than answering one prompt at a time. Two caveats belong in any honest write-up. First, Microsoft says availability depends on tenant, region, licence and admin settings, and we have not found a Microsoft statement confirming the Claude option for Hong Kong tenants specifically: check your own tenant’s model picker before you build a plan on it. Second, Claude requests from Copilot are routed to Anthropic-hosted infrastructure under Anthropic’s terms rather than staying inside Azure, which is a governance consideration your compliance team should sign off on.
Perplexity. Claude Sonnet 5 is selectable on Perplexity Pro, and Claude Opus 5 on Perplexity Max. More on pricing below.
What does not work from Hong Kong, despite what you may have read: Anthropic’s own apps and API, including the Claude Cowork desktop app, and (more surprisingly) Claude on AWS Bedrock, covered next.
Amazon Bedrock in Hong Kong: what works and what doesn’t
Amazon Bedrock is AWS’s managed service for foundation models, and on paper it looks like the obvious Claude route: Claude Opus 5 launched on AWS in July 2026. In practice, two things limit it from Hong Kong:
- No Anthropic models in the Hong Kong region (ap-east-1). The nearest Claude capacity is reached through cross-region inference via Sydney, Taipei, Tokyo, Seoul or Singapore. That part is routine; plenty of HK workloads already run in Singapore.
- Anthropic’s geo-restriction passes through Bedrock. Community testing from Hong Kong in August 2026 found Claude invocations returning a validation error naming “unsupported countries, regions, or territories”, regardless of which AWS region served the call. Bedrock appears to check where the connection originates, not just where the account is registered. We’d want to re-test before betting an architecture on either outcome, but the direction of travel matches the enterprise pullbacks above.
Bedrock is far from useless here. It carries OpenAI’s open-weight gpt-oss models (since August 2025), Amazon’s own Nova family, Meta’s Llama, Mistral and others, and 2026 reporting indicates OpenAI’s hosted frontier models have begun arriving on Bedrock as well, following the OpenAI–AWS compute deal. For an AWS-first Hong Kong business, Bedrock remains a strong platform; just don’t pick it for Claude.
Building on Azure, AWS or Google Cloud from Hong Kong?
Region selection, identity and cost control are standard cloud groundwork. We design and run it.
Microsoft Foundry: the developer route to GPT (and maybe Claude)
If you want the models as APIs rather than inside Office, Microsoft Foundry (the platform formerly known as Azure AI Foundry / Azure OpenAI Service) is the developer-grade equivalent of the Copilot story. Hong Kong isn’t an Azure OpenAI deployment region, but that’s a data-centre detail, not an access block: a Hong Kong organisation can subscribe and deploy the models in a nearby region such as East Asia, Singapore, Japan or Korea, and call them from Hong Kong. The catalogue includes the full GPT-5.6 family (gpt-5.6-sol, -terra and -luna), which means a HK developer can build directly against the same flagship model OpenAI won’t sell here first-party.
Anthropic’s Claude models also went generally available in Microsoft Foundry in June 2026, in both Anthropic-hosted and Azure-hosted flavours. Whether a Hong Kong tenant can actually deploy them is the open question; Anthropic’s regional terms may pass through exactly as they do on Bedrock, and we haven’t found a definitive statement either way. Treat Foundry as the proven GPT route and an unproven Claude route.
Google: Gemini works directly, Vertex AI for the API
Google took the opposite path to OpenAI and Anthropic: Gemini has been officially available to Hong Kong users since March 2026, no workaround required, which makes it the only frontier US assistant you can simply sign up for here. For developers, Vertex AI exposes Gemini via API from Google Cloud regions near Hong Kong, and its Model Garden lists partner models including Claude Opus 5. As with Foundry, we haven’t verified Claude-on-Vertex from a Hong Kong connection, and the Bedrock precedent suggests caution; Gemini itself carries no such asterisk.
Perplexity, Poe and the aggregator route
Perplexity works directly in Hong Kong (HKT even bundled twelve months of Pro for its mobile and broadband customers during 2025–26, though that enrolment window has closed) and remains the easiest way for an individual to choose which frontier model answers them. The catch is the paywall geometry. The US$20/month Pro tier includes GPT-5.6 Terra and Claude Sonnet 5, which is genuine frontier access at a reasonable price. But the flagship tiers, GPT-5.6 Sol and Claude Opus 5, sit on Perplexity Max at US$200/month per person. For one power user, fine; as a team’s primary AI tool, that’s Copilot money without Copilot’s tenant governance, so most businesses should treat Perplexity as a complement rather than the platform.
Poe (Quora’s multi-model app) is accessible in Hong Kong and offers GPT and Claude models under one subscription. OpenRouter does the same for developers as an OpenAI-compatible API over hundreds of models. Both are legitimate businesses, but they sit further from the model vendors than the Microsoft and AWS routes do, so check the current terms (and where your data goes) before putting work through them. Our comparison of which AI tools work in Hong Kong and China goes deeper on the data-governance side.
Cloudflare’s AI platform deserves a mention because it’s often suggested as an access route, and that’s half right. Workers AI hosts open-weight models (some of them frontier-class, none of them GPT or Claude), and AI Gateway, unified with Workers AI in August 2026, lets developers route, cache and even pre-pay for calls to OpenAI, Anthropic and others through one control plane. It’s a genuinely useful developer layer. But it’s a proxy, not a licence: whether an upstream provider serves a Hong Kong-origin call is still that provider’s decision, and Cloudflare doesn’t change it.
Why not just use a VPN?
Because every route above exists precisely so you don’t have to. A personal ChatGPT or Claude account run through a VPN breaches the provider’s terms, can be cut off without notice, and puts whatever your staff paste into it entirely outside your governance. Hong Kong’s regulators don’t ban AI tools, but the PCPD’s guidance expects organisations to control what data enters them, and for licensed firms the SFC expects the same in regulated work. Shadow AI over a VPN fails all of that at once. The fix is the one that runs through this whole guide: give people a sanctioned route that’s actually good, then back it with policy and security controls.
What a Hong Kong business should actually do
- Already on Microsoft 365? Copilot is the answer for most: frontier GPT by default, Claude Opus 5 in the model picker if your tenant shows it, enterprise data protection throughout. Confirm the Claude option on your tenant before promising it to anyone.
- Building products? Microsoft Foundry from a nearby Azure region for GPT; Bedrock or Vertex for everything non-Anthropic; test any Claude dependency from a Hong Kong connection before you architect around it.
- Individuals and researchers: Perplexity Pro is the best US$20 in Hong Kong AI; step up to Max only if you specifically need Sol or Opus 5.
- Whatever the route, govern it: an AI acceptable-use policy, DLP behind it, and no personal, confidential or regulated data into consumer tiers. That, more than model choice, is what separates safe adoption from an incident report.

FAQ: accessing frontier AI models from Hong Kong
Can I use GPT-5.6 in Hong Kong?
Yes. OpenAI still doesn’t serve Hong Kong first-party, but the GPT-5.6 family (Sol, Terra and Luna) is fully available here through Microsoft: inside Microsoft 365 Copilot for everyday work, and as APIs through Microsoft Foundry deployed in a nearby Azure region. Perplexity also offers GPT-5.6 (Terra on Pro, Sol on Max).
Can I use Claude Opus 5 in Hong Kong?
Yes, through two doors: Microsoft 365 Copilot’s model picker (including Copilot Cowork), subject to tenant and region settings you should verify on your own tenant, and Perplexity Max. Anthropic’s own apps and API remain unavailable here, and tests indicate the restriction is enforced even through AWS Bedrock from a Hong Kong connection.
Is it legal to access these models from Hong Kong this way?
Yes. These aren’t loopholes; they’re licensed distribution channels. Microsoft, AWS, Google, Perplexity and Poe all serve Hong Kong customers under their own terms, and the model vendors are paid through those channels. What breaches terms is going around the geo-block on the vendor’s first-party service with a VPN.
Why do OpenAI and Anthropic block Hong Kong at all?
Neither company has published detailed reasoning; both simply exclude Hong Kong from their supported-countries lists, decisions generally read as regulatory and geopolitical caution rather than anything Hong Kong has done. The practical point for a business is that it’s a vendor decision, not a Hong Kong ban: the territory’s internet is open, and the same vendors happily serve Hong Kong through Microsoft and AWS.
